DUMP WAGON.

Specification of Letters Patent.

Patented May 2, 1922.

Application filed July 2, 1912. Serial No. 303,255.

To all fic/Lomz't may concern.:

Be it known that I', HANS P. JENSEN- BERLUNDD7 a citizen of Denmark, residing at Lisbom Portugal, have invented certain new andV useful improvements in a Dump Wagon, of which the following is a specification.

This invention relates to motor-vehicles of the'tr-uclr pattern for hauling heavy loads, and has for one of its objects-to provide a device-of thischaracter having simple means for dumping the load by gravity only by changing the center of gravity of thev load to cause the body portion to automatically tiltto discharge 4the load'.

Another object ofthe invention is toprovide a device of this character having means for shifting the rear axles and carrying wheels forwardly of the body to bring the greater quantity of the load rearwardly of the axle and thus causing the body to autom'aticallyv tilt and dump the load.

lVith these and other objects in view the invention'consists in certain novel'features of construction as hereafter shown and described andthen specifically pointed out in the claims, and in the drawings illustrative of thev preferred embodiment of the invention.

`Figure l is a. longitudinal sectional elevation ofthe improved apparatus.

Figure 2 is a plan view partly in section with the load carrying. body or boX removed,

Figure 3 is a transverse section on the line 33 of'Figure l,

Figure 4 is a diagrammatic view on a smaller scale illustrating the arrangement of the` parts after the vehicleis disposed in dumping position,

Figure 5 is an enlarged sectional detail of a part of. the Vdifferential gearing. Y

The improved vehicle includes e1-,support-I ing. frame? formed in two portions.y arear-y ward port-'ion carrying the` rear car-rien wheels. the boX or load supporting portion of the device, and the motionftransmitting mechanism whereby the rear axle is operated, the forward frame portion carrying a drivers seat and hood together with the forward aXle and thesteering apparatus. The rear supporting Pertonfcomprises side members 10e-l1 Con-4 thev engine and the covering I nected at the rear ends by a transverse stay ll2 andL near their forward ends by a transverse stay 13.. Corner brace members 14 are likewise employed to connectthe members 13, l() and ll so that the rear portioncomprises a' very strong frame'. bers are preferably formed of I-beams and the members 12-l3 are Lbeams of suitable strength to withstand the strains to which they will be subjected.

rlhe forward v supportingv portion comprises side members 15-16 suitably connected and supported in the'usual mannerk and carrying the drivers seat 17 andthe hoodportion of the engine indicated at l8and thelradiator cover 19. The engine casing is indicated at 20 and supported in the usual manner from the frame members l5-l.6. The forward aXle is indicated at 2l with -the forward carrying wheels 2.2-23 connected thereto in the usual manner by the `stub-axles indicatedv 232e the. steering arms .Q5-26, and the connecting rod at Q7. The side members .lOdll extend forwardly of the rear portions of the side members 15-16 and are swingingly coupled to the side members-15 and 16 of the forward frame members as shown more clearly in Figure 2. The coupling devices between the forward and rearward side` members of the frame are substantially alike and the de scription of one will suffice for both. The members 15--16 are each..provided with a stud 28 and the adjacent portions .of the members lO-ll are each provided with a socket member 29 in which the studs bear as illustrated in Figure 2. By this means the frame members are capable of being upwardly when the dumping action occurs as hereafterv` described.

Bearing y upon the forward portion of member: l0 is plateA 30 which extends over the.v adjacent portion of the members '15. while asimilar plate 3l is connectedto the forward portion of the member ll andextends overthe adjacent portion'of the rniemberY 16. The plates Bil- 3l are disposediforwardly of the socket devices 28 and so that theyoperate as stops-tolimit the downward move- :ment of the members 10-15 and l1-l6,

while atthe same time they do not interfere with the upward movement or buckling action of the members during the dumping operation. Bearing over the members 15-16 is a stay. rod 32 connected tothe members l-lby Uk-bolts 5S-34. yThemember 30 is provided The side memv buckled y with a forwardlyj directed overaxle to a forward position to bring the or portion of the load rearwardly of the rear axle.

Any suitable means may be employed for moving the rear axle 37 and its attachments forwardly or toward the forward axle or moving the forward axle and the loaded body toward the rear axle, to cause the dumping of the load.

The rear wheels may be manually rotated toward the forward axle, or the rear wheels may be blocked and the loaded forward part of the vehicle moved rearwardly until the load overbalances, but as the manner of changing the center of gravity of the load forms no part of the present invention, it is not thought necessary to further describe the same.

When the load is dumped the forward portion of the members 10-11 are elevated upon the joints 28 and 29 and likewise throw the rear portion of the forward part of the device upwardly as indicated in Figure 4, but this will not interfere with the operation of the device. Suitable means should be provided for temporarily coupling members 51-52-53 and 54 to the members l() and 11, and an improved means consists of set screws as indicated at '75.

The improved device is simple in construction, can be applied without material structural change or modification to truc-ks and automobile operating devices of various forms and sizes and to adapt the device to carry any size of load.

For the purpose of illustration the improved device is shown applied to a convene tional form of automobile structure, but it is to be understood that it is not desired to limit the invention to any specific form of motor truck or vehicle.

Having thus described the invention what is claimed as new is:

l. A vehicle of the class described comprising a forward frame carrying forward bearing wheels, a motor mounted on said forward frame, a rear frame swingingly coupled to the forward frame and including side members in parallel relation, supporting devices slidably bearing on the side members of said rear frame, a rear axle carrying rear bearing wheels, springs connected to said axle and respectively to said supporting devices, a transmission device carried by the rear axle, a drive shaft extendingfrom said motor, and slidably engaging said transmission device, whereby when the hingedly united frames are broken upwardly the rear axle and its bearing wheels will be moved forwardly without cramping the parts.

2. A vehicle of the class described comprising a forward frame carrying forward bearing wheels and a motor, a rear frame pivotally united to said forward frame, a rear axle supporting rear carrier wheels, means for coupling said axle for movement longitudinally of the rear frame, a drive shaft mounted for rotation upon the rear frame and extending longitudinally thereof, a transmission gear device carried by the rear frame and through which the drive shaft is slidably disposed, and means for operatively coupling the motor to the shaft.

In testimony whereof, I aflix my signature hereto.

HANS JENSEN-BEARLUNDD.
